STEAM 'NOZZLE Original application filed. April 17, 1930,

. 1931. serial This invention relates to an improvement in steam nozzles particularly intended for steaming or sterilizing the interior of milkcans or other like hollow containers. rlhis application is a division of my co-pending ap'- plication Serial No. M -963, filed April li, 1930.

The object of the invention is to provide an improved steam nozzle, of a construction enabling it to be inserted within a milk-can or other like container for the purpose of inject.- ing steam therein to sterilize the can, which will direct steam free from condensate again the inner surfacesof the can walls. The invention also contemplates the prcvisi on of means by which the condensate carried by from the to prevent its interference with the introduction of live and relatively dry steam against the inner faces of the can walls.

ln the preferred form of the inventi fn shown in the accompanying drawing, Fig. is a vertical sectional view of a steam nczzle made in accordance with this invention, and Fig. 2 is a plan view of the same.

The nozzle forming the subiect-matter of this invention is usually inserted within the can to be subjected to the action ofsteam to kill any deleterious microorganisms adhering thereto. The nozzle is provided with a central perforated pipe 3, the top or upper end of which is closed by a threaded cap ll. rllhe pipe 3 is located in the bottom of a cylindrical shell or casing 5 which is longer and of greater diameter than the pipe 3 and extends well up beyond the upper end of the pipe 3. vThe casing 5 is open at its upper end and closed at its lower end, with the exception of several small openings or drain holes 6 there.- in. Thercasing 5 is supported at its lc'wcr end by brackets 7 which are bolted at S to a air of spaced supporting bars 9.

The center of the bottom of the shell or casing 5 is pierced to receive the lower end of the pipe 3 which is secured to the upper end of a steam-supply pipe l0. The pipe l() is provided with a suitable valve, not shown, and when the valve is opened the steam rushes up into the perforated pipe 3, carrying with it any condensate which has gathered in the nozzle casing Serial No. 4

During the steaming of the interior surfaces of the can, the nozzle will, of course, be inserted up in the can. The condensate carried by the steam will impinge against the inner walls of the casing 5 opposite the apertures ll and will fall down onto the bottom of the casing and will run out through the holes 6 therein. Consequently only steam freed from condensate will be driven against the inner surfaces of the can and it will therefore be understood that a very effective sterilizing action will be obtained. The drip from the bottom of the casing 5 may fall into a suitable receptacle located beneath the nozzle or on the floor.

Means for steaming and sterlizing the inner surfaces of a hollow receptacle by di recting substantially dry steam thereagainst comprising a nozzle including an upright pery forated pipe cylindrical throughout its length and closed at its upper end, and an upright casing cylindrical throughout its length surrounding the perforated pipe in spaced relation thereto, the upper end of the casing beingy unobstruetedly open and the -lower end of the casing being closed by a `bottone through which the pipe projects upwardly into the casing, the bottom o-f the casing having drain apertures therein an the perforations in the pipe extending from the bottom wall of the casing to the upper end of the pipe.

2. Means for steaming and sterilizing the inner surfaces of a hollow receptacle by directin substantially dry steam thereagainst comprising a nozzle including an upright perforated pipe cylindrical throughout its length and closed at its upper end, and an upright casing cylindrical throughout its length surrounding the perforated pipe in spaced relation thereto, the upper end of the casing being unobstructedly open and 5 the lower end of the casing being closed by a, bottom through Which the pipe projects upwardly into the casing, the bottom of 'the casing having drain apertures therein and the perforations in the pipe extending from the bottom Wall of the casing to the upper end of the pipe, and the casing being substantially twice the length of the pipe whereby entrained globules carried upwardly by the steam Will impinge the side Wall of the casing for deposit thereon.
